So I've re-noticed something recently which is probably old hat to most here, but...
Price is relative, right? Like, I may look at a good Easton or Worth baseball bat priced at $399 and think, "Umm, that's way too expensive." Or I may think about getting a dedicated gaming laptop, but balk at the $899 price tag. Or worry if I'm paying too much for a new Shop-Vac when I could get a better deal at Ye Olde Big Box store.
But I'll cheerfully Watch and even Make Offer on a $2000 piece of ho-end equipment after researching and/or hearing it. That much would pay for the Easton, the gaming laptop, and the Shop-Vac - with some change to spare, and yet that perspective is skewed when it comes to stuff on Audiogon - whether I'm buying or selling.
I'm toying with getting an Oppo 105 and since most of them are in the $850 range, I'd honestly feel guilty if I bid anything under $700. Like, I;d feel obligated to send a note of explanation with the bid. Same with things I'm selling, especially if I've done the Bluebook research.
I'm glad Agon has that 55% Lowball cut-off, though I think that's much too low. If someone offered me 55% of my asking price, their bid would be ignored without a doubt.
